How to get Last N Characters in String in Rust ?

Answer

To get the last N characters of a given string in Rust, you can use the `slice` method with negative indices.

✐ Examples

1 Last 5 Characters of "Hello World" String

In this example,

We create a string reference named str1 with a string value of "Hello World".
We then use &str1[str1.len() - 5..] to get the last 5 characters.
Finally, we print the last 5 characters.

Rust Program

fn main() {
    let str1 = "Hello World";
    let last5_chars = &str1[str1.len() - 5..];
    println!("Last 5 characters of the string are: {}", last5_chars);
}

Output

Last 5 characters of the string are: World

2 Last 3 Characters of "apple" String

In this example,

We create a string reference named str2 with a string value of "apple".
We then use &str2[str2.len() - 3..] to get the last 3 characters.
Finally, we print the last 3 characters.

Rust Program

fn main() {
    let str2 = "apple";
    let last3_chars = &str2[str2.len() - 3..];
    println!("Last 3 characters of the string are: {}", last3_chars);
}

Output

Last 3 characters of the string are: ple
